IV06178: IMPORTVG HANGS WHEN RUN FROM A SCRIPT APPLIES TO AIX 7100-00

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• If running importvg from a script, it may hang. The
  cause of the hang is because the trustchk process,
  which is called during the execution of importvg, is
  hung.
  
  If a truss is taken of the importvg process, the last
  thing seen will be:
  
  16646306:       71237679: 88.5006:        kfcntl(0,
   F_SETLK, 0x2FF214C0)
  (sleeping...)
  
  
  kdb will show a stack similar to this:
